尽管全球产生了大量的非危险工业废物（NHIW），但系统的NHIW再利用政策仍然滞后，这主要是由于对产生量、位置、化学成分和未来趋势的零碎理解。在这里，我们演示了如何使用工艺工程和经济预测的信息来估计美国2亿至3亿吨NHIW中的矿产和能源流量。我们估计，NHIW中所含的矿物质约为1亿吨，从1990年到2016年，每年的潜在电量为2000亿千瓦时。预计从2017年到2050年，这两个数字都将增长约50%。电势和大量矿物质含量（例如，CaO和SiO2）与这些资源的总消耗水平相比是适度的（
Despite the large volume of non-hazardous industrial waste (NHIW) being generated globally, systematic NHIW reuse policies are lagging, largely owing to piecemeal understanding of generation volumes, locations, chemical constituents, and future trends. Herein, we demonstrate how to estimate the mineral and energy flows embedded in the 200-300 million tonnes of NHIW in the United States using information from process engineering and economic projections. We estimate that the minerals contained in NHIW are on the order of 100 million tonnes and with electricity potential lectricity at 200 billion kWh annually from 1990 to 2016. Both are expected to increase by roughly 50% from 2017 to 2050. The electricity potential and bulk mineral contents (e.g., CaO and SiO2) are modest compared to the total level of consumption of these resources (
